This Week in the Eastern Caribbean

The Eastern Caribbean is experiencing typical transition season conditions as spring moves toward early summer. Temperatures across the region have ranged from 20°C68°F in the northern islands to 31°C88°F across the central and southern zones. Humidity levels remain elevated at an average of 81 percent, contributing to scattered cloud development and occasional shower activity.

Wind speeds have been moderate, with most areas experiencing easterly flows, though exposed northern locations recorded gusts to 43 km/h26 mph. Sea conditions remain gentle, with wave heights between 1 to 2.1 metres3 to 7 feet, making conditions favorable for maritime activities across the region.

This Week's Outlook

Moisture patterns are becoming increasingly important as the season transitions. The Southern Caribbean, from the Windward Islands southward through Trinidad and Tobago, will see heightened chances of showers today and tonight as atmospheric moisture and instability concentrate in that area. Residents and visitors in these zones should remain prepared for brief periods of moderate rainfall and possible temporary travel delays.

In contrast, the Leeward Islands and areas west toward Puerto Rico will experience considerably drier conditions over the coming week. Low atmospheric moisture and limited instability over the northern and western portions of the Eastern Caribbean mean that shower activity will remain minimal in those zones. Prevailing easterly winds will continue to steer moisture patterns, with the windward slopes of elevated terrain remaining more susceptible to occasional precipitation than exposed southern and western coastal areas.

Atmospheric pressure remains stable near 1014 mb, with no tropical systems threatening the Atlantic basin, allowing typical seasonal weather patterns to dominate.

Looking ahead through the week, conditions will gradually stabilize as the initial moisture surge moves through the southern islands. Daytime temperatures should remain in the typical range for this season, with coastal areas generally warmer and higher elevations slightly cooler. Nighttime conditions will offer some relief from the humid daytime heat.

Sea conditions are expected to remain manageable for maritime operations, though small-craft advisories should always be consulted before heading offshore. The lack of organized tropical activity across the Atlantic basin suggests a quiet weather period for the Eastern Caribbean heading into the latter part of April.
